According to a recent inventory (Tansey et al. 2008), wild land fires and other biomass fires annually burn a total land area of between 3.5 and 4.5 million km2, equivalent to the surface area of India and Pakistan together, or more than half of Australia. This makes it one of the most spatially prevalent hazards after drought.

Emissions from biomass burning inject pollutants into the atmosphere, as well as greenhouse gases (GHG). The IPCC attributes 17.3% of total anthropogenic emissions to biomass burning, making it the second largest source of GHG from human activities after the burning of fossil fuel.
